A bit ridiculous the BBC listings refer to this as "Season 1". Every other show on the BBC, including US series, are referred to as "series" not "season".

The series which aired in 1963 is also officialy known as Season 1. In this case, that would be to differentiate from Series 1 - which aired in 2005.

I personally call the Disney+ era Season 1 that starts next week Series 14, as it is the 14th series of the revived series.

It makes it less confusing for me, especially given that as of next Saturday, between the original series and the revived series, there's going to be 40 overall series/seasons of Doctor Who.
